This is my first year on a road bike and I have been loving it. I have seemed to get into it fairly quickly, I have done a few races already and am going to do many more as year goes on. Any way I bought a Cannondale Cyclocross Disc because I was riding some dirt roads and what not early in the year. Now I am riding only pavement so I have it set up like a road bike. But now I have come to the point where I am thinking of upgrading to a Dura-Ace kit (bike currently has Ultegra Setup) . So just wondered what you guys thought, should I put money into a Dura-Ace kit for my Cyclocross or should I buy a road specific bike and maybe upgrade that to Dura-Ace farther down the road. I mean other then maybe a few pounds what would I be gaining by going with a road specific bike?

Any suggestions/info would be greatly appreciated.
